Josh Rouse-The WB.com

In the Roswell episode “Heart of Mine,” Sean bares his soul to Liz in the bowling alley, backed by the swelling sounds of Josh Rouse. His second album, Home, is as simple and comfortable as its name suggests. Acoustic melodies are augmented by haunting strings and soft horns that give the album a nice introspective feel, which is often echoed perfectly in the lyrics. This is not a party CD, but it is the perfect background music for a mellow night at home.
